Native Bovine Deoxyribonuclease I

Cat No.
NATE-0198
Description
Deoxyribonuclease I (usually called DNase I), is an endonuclease coded by the human gene DNASE1. DNase I is a nuclease that cleaves DNA preferentially at phosphodiester linkages adjacent to a pyrimidine nucleotide, yielding 5'-phosphate-terminated polynucleotides with a free hydroxyl group on position 3', on average producing tetranucleotides. It acts on single-stranded DNA, double-stranded DNA, and chromatin. In addition to its role as a waste-management endonuclease, it has been suggested to be one of the deoxyribonucleases responsible for DNA fragmentation during apoptosis.
Abbr
DNASE1, Native (Bovine)
Alias
DNASE1; DNase I
Source
Bovine pancreas
Species
Bovine
Applications
Used for the removal of DNA from protein samples. DNAse I is used to nick DNA as a first step to incorporate labeled bases into DNA. The enzyme from Creative Enzymes has been used in the processing of rat brain tissue. This study showed that axonal growth on astrocytes is not inhibited by oligodendrocytes. In another study, thawed fixed samples of E. coli were digested with DNAse I from Creative Enzymes along with other enzymes. The digestion was done before permeabilization and staining of the nucleic acids. Deoxyribonuclease I from bovine pancreas has been used in a study to investigate a two-dimensional zymogram analysis of nucleases in Bacillus subtilis. Deoxyribonuclease I from bovine pancreas has also been used in a study to investigate the effects of minor and major groove-binding drugs and intercalators on the DNA association of minor groove-binding proteins RecA and deoxyribonuclease I.
